ATP-dependent chaperone, which plays an essential role in the cytoplasmic maturation steps of pre-60S ribosomal particles by promoting the release of shuttling protein RSL24D1/RLP24 from the pre-ribosomal particles (PubMed:35354024). Acts together with AFG2B, AIRIM and CINP (PubMed:35354024). May be involved in morphological and functional mitochondrial transformations during spermatogenesis (By similarity).
